Sure, I'll try. Keep in mind that I will only mention the benefits. Read other sources for the disadvantages so that you can make a decision. * America feels that caring for the environment is important so there are laws preventing companies from polluting "too much". In China they don't have as strict laws. Therefore manufacturing in America is more environmentally friendly than in China. Therefore, it is worth the tax on the consumer to keep the environment cleaner. * America believes that people deserve basic workers rights that are not offered in China. Without tariffs companies offering workers rights could not compete against those who aren't. * In the case of a war, China may stop providing American with steel when they need it the most. By encouraging Americans to make steel plants, in the case of a war, America will be able to produce the steel. * China is very powerful, so much so that they could be a threat to America. However most of China's economy comes from export. Tariffs will hurt America, but will hurt China much more, thereby making them less of a threat against America's world dominance. * Canada tarrifs some of Americans goods. That is not good for America. By retaliating with tariffs, Canada may agree for both sides to stop tarrifs. (that is most likely not applicable for this case since Trump didn't announce that as his demands)
